I just searched and found it, and browsed through it. There are some real howlers: the NFL is the most popular league in the world, no playoffs in European football means that effectively all of the teams "make" the playoffs, the trophy gets "handed" to the team with the most points instead of having playoffs, etc.
Sometimes I think the internet is one big billboard set up for people to declare: "I'm stupid."
